摘要: A newly constructed university building was selected for targeted assessment of changes in the levels flame retardants and legacy contaminants during installation equipment, furniture, electronics, first year use. Indoor air samples were collected several periods intensive equipment to determine a relationship between introduced concentrations profiles indoor air. Samples analyzed polybrominated diphenyl ethers (PBDEs), hexabromocyclododecanes (HBCDDs), new types retardants: brominated (BFRs) organophosphate esters (OPEs). Additionally, typical outdoor such as polychlorinated biphenyls (PCBs) organochlorine pesticides (OCPs) also comparison. From set 90 compounds here, hexabromobenzene (HBB) tris(2-chloroisopropyl)phosphate (TCIPP) showed significant concentration increase computer operation, suggesting emission by operating computers, while an order magnitude tris(1,3-dichloro-2-propyl)phosphate (TDCIPP) tri-m-cresyl phosphate (TMTP) observed after furniture carpet room, or source. However, majority had no systematic change installation, indicating that sources target or, source introduction not reflected concentrations. Generally, low compared their novel alternatives observed.
